You can get unlocked android phones and install whatever you want. But the reality for our parents / grandparents etc is that the folks who want to have root on their device want to scam them, auto bill them with non-cancelable billing etc etc etc, market to them by tracking everything, turn all their data over to the govt.
We have basically one company who is trying to do a consumer / privacy first play. They went toe to toe with the DOJ to avoid unlocking the phone of a known shooter.
As more and more of our life lands on these devices, I think this is the smart play. Go use another phone if you don't like it.
